This fastener features a cup point tip that bites into mating surfaces to resist rotation and axial movement under load. It is driven with a 5\/64-inch hex key and meets ASME\/ANSI B18.3 and ASTM F912 standards. The 8-32 UNC thread and 1\/4-inch overall length make it well suited for light-to-medium duty clamping applications in mechanical assemblies. Each package contains 50 pieces.\u003c\/p\u003e\u003cp\u003eCup point set screws like the MP40339 are widely used across HVAC, refrigeration, electrical, and general mechanical applications wherever a flush or recessed fastener is required. Typical uses include securing pulleys, collars, gears, and knobs onto shafts, as well as locking adjustment mechanisms on equipment. The Grade 8 alloy steel construction provides higher tensile strength than standard steel fasteners, making these appropriate for applications with moderate vibration or clamping force requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point geometry bites into shaft or mating surface for positive grip and slip resistance\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction offers high tensile strength for demanding clamping applications\u003c\/li\u003e\n\u003cli\u003e8-32 UNC thread provides broad compatibility with standard tapped holes in mechanical assemblies\u003c\/li\u003e\n\u003cli\u003e5\/64-inch hex drive allows installation with a standard hex key or Allen wrench in tight clearances\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n\u003cli\u003eSold in a 50-piece package for bench stock and service inventory\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 8-32 UNC set screw for use in any tapped hole conforming to ASME\/ANSI B18.3 specifications with a 5\/64-inch hex drive socket.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSet screws are installed by mechanical technicians using a 5\/64-inch hex key torqued by hand to manufacturer-specified values for the thread size and grade. Always de-energize and lock out equipment before accessing rotating components such as pulleys or collars. Avoid over-driving, which can strip the hex socket or damage the mating surface. Refer to applicable equipment service documentation for proper seating depth and torque requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.25 inches (overall)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 5\/64 inches (0.0781 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MP40339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701912830258,"sku":"MP40339","price":14.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/value-collection-mp40339-set-screw-8-32-x-1-4-in-cup-point-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
